Right Stick Crouch?!?!

The game is absouloutly amazing but... I feel like I'm going out of my way to slide, if there was an option to either customize your own controls or switch [i][b]B[/b][/i]button and [b][i]Right Stick[/i][/b], I'm sure a lot of players will be happy![spoiler]Yes i realize its a cod feature, but i still think is should at least be an option[/spoiler]
